8N Won't fire

My 8N was running fine all spring. I ran out of gas about a week ago, and I forgot to turn the key, therefore, running my battery dead. After I charged it, & filled it with gas, it wouldn't start. The carburetor is getting gas, so I checked the spark at the plugs. I have none. I pulled the distributor cap (front mounted) & I found the main lead on the rotor bent. I replaced the rotor, and it still wont fire. I noticed the distributor cap is stratched inside from the bent lead, and one of the ports for the spark plug is broke (just the plastic). Also, the distrubtor cap interior, the brass contacts are slightly scraped.

I would like to have some input. I checked the points, and they look okay & open. I was going to file & regap the points. Then check the spark at the plugs. Do I also check the spark at the coil? If so, how? Also, what is the spark plug numbering order? Is it 1-4 from the front to the back, back to front, or another combination?

Thanks for you help.

Been there done that. A couple of week ago I left the key turned on (after I ran gas out of carb.) for a couple of hours and the bottom line, replaced points and condenser(condenser came with pionts) from FH dealer. And the coil since it blow up ( top came off the cylinder part). Firing code 1,2,3,4 front to back. $7 points and condenser and $17 coil non dealer.

The firing order on and 8n is 1 3 4 2 with #1 starting at the rad. It looks like you burn the points when you left the swicth on.Give it a good tune up that should fix it right up.Good luck. Dick

Dick, I believe you made a typo on the firing order. I think you transposed the 3 and the 2. Happens to me too sometimes.

Also check continuity in your key switch. Check for good contact in the bottom of the coil, if the coil is still good.

If the distributor cap has a problem, then replace the cap. Do not file the points. You are only looking for more problems if you do. If the points look pitted, then replace them. I suspect that your coil may have given up the ghost. Firing order is 1243. It is hard to check for spark at the coil if you have the front mount distributor, otherwise, take the center coil lead and hold it about 3/16 of an inch from a good ground and have someone crank the engine while you check for a nice blue spark. Look for 3 - 4 volts at the coil with the points closed. Of course, this will not detect shorted turns in the coil.

Check spark at coil by removing wire from distributor and hold it near the block and push the start button. You should have a good spark. This happend to me and it turned out to be the main wire from the coil to the distributor. Check your wires to makesure they didn't fry.
Clean off distributor wires.
Check your negative and positive at the battery to makesure you have good connections.
Good luck
